  1. Wtf is this smell?

    W140 S-Class
    It looks like any lines in that area from the ASR/SLS should be hard lines. There are some flexible lines near the tank, and the leveling valve, but that appears to be all. Try taking a couple of drops of the hydraulic fluid and drop them on an exposed exhaust manifold with the engine running...
  2. 50 mph, The Dreaded Vibration

    W140 S-Class
    Roadforce balancing my Eltanins with Continental tires got rid of my shimmy issues. Before I did that, readjusting front wheel bearing freeplay made a big difference also. I still get shake for 5 miles after letting the car sit overnight, until they get themselves round again. I thought the...

    EPC says the 8x16 wheels came with different tires as well. Why we didn't get the 8.5x18s like the UK did, I don't know. Doesn't make sense. Jon

    W140 S-Class
    None of those are standard wheels. In fact the page says "upgrades". Edit: I stand corrected. While my 95 S600 came with 7.5x16 all around, Mercedes EPC says model year 95 up came with 8.0x16 on the rear only. But then it says 96 and up came with 7.5x16 all around, so who knows. There were a...
  5. 50 mph, The Dreaded Vibration

    W140 S-Class
    I have 94 and 95 S600 US spec coupes, and both came with 7.5x16" wheels front and rear, just like the sedans. Some Euro coupes came with 8.5x18" wheels front and rear. I have a UK brochure indicating those were standard there. I'm not aware of any US coupes that came with staggered wheels from...
  6. Vacuum lines

    W140 S-Class
    At the connector for the line coming from the floor to the seat? A picture would help. Jon
  7. Pre lubing of New Genuine Mercedes Window Regulator; Front Right for Power Window P/N: 140720304

    W140 S-Class
    Absolutely lubricate it liberally in every area that rotates or slides. W140 windows are extremely heavy, and any friction will make regulators fail quickly. Use a quality synthetic grease that won't harden with age. Jon
  8. Vacuum lines

    W140 S-Class
    Cap it either at the pump, OR the front of the seat. There should only be one line at the front of each seat for the bladders. Jon
  9. 50 mph, The Dreaded Vibration

    W140 S-Class
    Any looseness anywhere can be excited vibrationally by any number of things. How they all combine on a given car and manifest themselves is unique. Something about the W140 makes it very sensitive to vibrations. Jon

    W140 S-Class
    The other thing that makes an amazing amount of difference is wheel bearing adjustment. Mercedes has very tight tolerances for this, and it can make a world of difference if they are even slightly loose. You really need a dial indicator and magnetic stand to measure it properly. Jon
  11. heater control

    W140 S-Class
    Left front of the engine compartment. Looks like the photo below. Shorter cylinders are solenoids that control the heat for each side of passenger compartment. Taller cylinder is pump for circulation coolant for the engine after shutoff and for heat after shutting off the car. Solenoids can go...
  12. Dead Battery, Trunk Locked - Alternator Jumpstart??

    W140 S-Class
    I don't think it's just the radio. That was just an example. Whenever you leave the car for more than a few days, put a float charger on it. Jon
  13. Dead Battery, Trunk Locked - Alternator Jumpstart??

    W140 S-Class
    If you pull the key out, then put it back in, you are ok, as long as you don't turn it. If you left the key in the off position, but didn't pull it out, you leave some systems activated, such as the radio. Jon
  14. Ongoing ASR issue when cold.

    W140 S-Class
    Try removing and reseating the ASR and ETA modules. Make sure they are fully seated, using a rubber mallet if you need to. I had a similar issue, and that cured it for me. Jon
  15. Vacuum lines

    W140 S-Class
    You can replace them with generic plastic line available at auto parts stores. Mercedes sells the line in bulk form, but the last time I tried to buy some, different colors weren't available, just generic translucent white. They do sell the molded rubber end fittings, sometimes with needed...
